I have c# tcp server that can accept clients from just the same machine (a.k.a. 127.0.0.1 ip address) but cannot accept clients from the same wi-fi private network (a.k.a. 192.168.1.x even if it's the machine's private address!). I figured to use arp -a to see what private ip addresses that my machine sees and the results are
Internet Address Physical Address Type
192.168.1.1 5f-f2-3c-b7-1a-03 dynamic
192.168.1.255 ff-ff-ff-ff-ff-ff static
224.0.0.2 01-00-5e-00-00-0c static
224.0.0.22 01-00-5e-00-00-a6 static
224.0.0.251 01-00-5e-00-00-ee static
224.0.0.252 01-00-5e-00-00-ad static
239.255.255.250 01-00-5e-7f-ff-76 static
255.255.255.255 ff-ff-ff-ff-ff-ff static
I really didn't fully understand it, but how can I make my computer be private server that can accept any coming clients from my router? and if possible, I want the solution to be changing settings and not installing other libraries or programs.
